OIL-CAN.

SPECIFICATION forming partof Letters Patent N o. 543,472, dated July 30, 1895..

Application tiled April 23, 1895.

To all whom it may concer-m Be it known that I, GEORGE A. FOSTER, a

` citizen of the United States, residing at Fulton, county of Callaway, State of Missouri, have invented a certain new and useful Im provement in Oil-Cans, of which the following isa full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, wherein the ligure represents a vertical sectional view of my improved can.

This invention relates to a new and useful p, improvement in oil-cans designed particularly for lubricating purposes, the object being to construct a can of the class described whereby i air may be forced therein to and compressed,

l exerting a pressure on the oil which is forced out ofthe spout, said spout being controlled by a regulating-valve.

In the drawing, A indicates a suitable can or receptacle, the bottom of which is elevated and receives an air-pump, the raised bottom affording space for the handle of the pump,

. enabling the can to be set on its bottom.

p B indicates the cylinder, which is provided y -with threads on its lower end and screwed into the raised bottom. A ange is arranged at the lower edge of the cylinder,which clamps a packing-ring therebetween and the bottom.

` `13o A perforated plate C is secured to the lower y valve F is arranged on the plunger to control the passage of air through the hollow rod.

The upper end of the cylinder is formed with an opening which is controlled bya Valve G, which is mounted in a cap arranged above the cylinder, saidA cap being formed with lateral openings,which permit the air forced beyond the valveGr by the plunger to pass to the interior of the can. A

H indicates a spout, the opening to which is controlled by a plate l, faced with suitable packing, which plate is mounted upon two or more rods J, whose upper ends are secured to a disk K, through which the spout passes.

Serial No. 546,851. (No model.)

A spring surrounds the spout and bears against the disk and tends tohold the same up and close the opening to the spout. The rods J preferably pass through packing-boxes formed in the base of the spout, which base is formed with screw-threads by which it is secured to the can.

In operation, to till the can, it is only necessary to remove the spout and its associate parts, whenaccess may be gained to the interior, as usual. To compress air within the can so as to place the oil under pressure, it is only necessary to reciprocate the plunger a few times, when the device is ready for use. When it is desired to obtain oil through the spout, the disk K is pressed inwardly, which opens the spout and permits the oil to ow therefrom under pressure. Itis, of course, understood int-his connection that the can is tilted a little to one side or inverted, as the case may be, otherwise the compressed air only would pass through the spout. the oil does not flow actively, it is only necessary toreciprocate the plunger a few times to give it life.

The advantages of putting the oil 'under pressure are many, the chief one being that cold orthick oil may be forced to iiow readily without the necessity of heating. p

v I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be madel l. The combination with a can, which is formed with an elevated aperturedbottom,l

affording a recess to receive apiston-handle, of a cylinder secured in said aperture, an in wardly-opening Valve closing the inner end of the cylinder, a plunger arranged within the cylinder, an inwardly-opening Valve on4 the plunger and a handle for operating the plunger; substantially as described.

2. The combination with al 'can having a spout and. a raised apertured bottom, of a spring-pressed regulating valve to control the emission of oil through the spout, a cylinder mitting the compressed airin the cylinder to pass into the can, and a regulating valve for controlling the emission of oil through the spout; substantially as described.

In testimony whereof I hereunto affix mysignature, in presence of twowitnesses, this 15th day of April, 1895.

GEORGE A. FOSTER.
